El manual esta muy detallado, los numeros de partes y los esquemas de despiece son correctísimos y muy claros, tanto para los técnicos experimentados como para los novatos.
 ;
Ottima qualità grafica e completo nelle notizie. Costo abbastanza contenuto.
;
Great and quick support. The maual was exactly what I was looking for and my problem
solved. Many thanks.

Very good service Within one day i received a pdf of the users manual and electric circuits so I was able to measure the different voltages in the printed circuit and find out the fault Payment was also reliable and easy.Without the manual i could not have repaired.So thanks to "Search for a manual"

you are doing great job guys.....my father ask me to find out the schematics of Sony KV25R1D to sort out the problem ..(he was electrical technician, and excperianced with TV and simillar stuff). finally he found the cause and change all necessary parts....now he has got working old dog..and is very happy!!... thank you all.. NB..he also saved the repair cost.

7.1.6 OUTLINE OF THE WAVEFORMS RECEIVED BY THE DSP SECTION
A
The illustrated signal waveform is an example of the signal waveform when a Dolby Digital (Fs = 48 kHz) signal is received. It must be noted that a frequency (waveform period) other than that of the Master clock supplied to the DSP section changes depending on the format of input signals or mode of the unit. It must also be noted that the waveform being observed changes depending on the environment of the measurement system (high-frequency characteristics of an oscilloscope or a probe, grounding method, etc.). (The numbers 1-9 of the waveform names correspond to those of the waveform data and those in the clock flowchart.)
S/PDIF signal waveforms
� Flow indicated with " " in the clock flowchart Aperiodic rectangular-wave signal 1 COAXIAL or demodulator input: Amplitude of approx. 5 Vp-p (when the signal is input to IC101) 2 OPTICAL input: Amplitude of approx. 4 Vp-p (when the signal is input to IC101) 3 OPTICAL output: Amplitude of approx. 3.3 Vp-p (when the signal is output from IC101) In the following waveforms, the amplitude of all clocks is approx. 3.3 Vp-p.

DSP master clock waveform
� Flow indicated with " " in the clock flowchart Aperiodic rectangular-wave signal 9 Master clock waveform (for DSP) Only this clock operates on a fixed frequency: 12.5 MHz (80 ns).
